Prince Adalbert Ferdinand Berengar Viktor of Prussia (14 July 1884 – 22 September 1948) was the third son of Wilhelm II, German Emperor, and Augusta Victoria of Schleswig-Holstein.

He was born in the Marmorpalais of Potsdam in the Province of Brandenburg, where his parents resided until his father acceded to the throne as Emperor Wilhelm II in 1888.

He spent his childhood with his siblings at the New Palace, also in Potsdam, and his school days with his brothers at the Prinzenhaus in Plön in his mother’s ancestral Schleswig-Holstein.

His bride was Princess Adelheid "Adi" of Saxe-Meiningen (16 August 1891 – 25 April 1971), daughter of Prince Frederick and Countess Adelaide of Lippe-Biesterfeld.

They married on 3 August 1914 in Wilhelmshaven, Germany, and had three children, five grandchildren, six great-grandchildren and two great-great-grandchildren: Adalbert died in La Tour de Peilz, Switzerland, aged 64.
